I ripped apart my prior bosoz and installed the new boards. Becuase every square mm of space was used, I had to make an external power supply, and suddenly space was not a problem.

This is dual mono, 2 balanced inputs, 2 SE inputs, 2 bal output, 2 SE outputs in parallel. There is also 1 SE output using INA134s, and one of the inputs is a DRV134 input. There are a LOT of ultrabright LEDs, each one has its own current limiting resistor, and many have variable resistors for this. All can be switched off, to reduce "noise" although you can't measure or hear any noise increase with all the LEDs on.

So on with the pics, many are very large hires, and you can see them at my website:

I felt kind of guilty ripping apart my hand soldered perfboards and using PCBs, but what the heck, progress is progress right? If it sounds better it will be worth it, but have not listened very much yet.

The signal path is actually quite short, inputs to 4PDT relay board to preamp boards, to vol control, to output, using cloth/silver or teflon/silver wires. The mess'o'wires are mainly due to the momentary pusbutton switches, which supply a 9 conductor (8 bit) "word" to the relay boards to "set" and "reset" all the latching relays depending on what button you hit. There are 2 sets of latching relays, one for the inputs and one for the LED that lights above the currently active selection. Ok, there are a lot of other wires too, for the LEDs and INA and DRV boards.

What can I say? This is DIY and you get to make stuff like yout want to, and I wanted a lot of lights. Tacky? Yes. Just like I wanted it? yes! ok, not really, didn't know that they would be that bright! You ain't gonna see one of these in a store!
